The most likely error is that the wire going to the light that stays on is contacting one of the live wires. To check, disconnect all the wires from each other, turn on the breaker and use a voltage tester to identify the live circuit wire.
Why does my light stay on when switch is off?
If a light switch is turned off, but the light still stays on, it could be because the light is connected to a hot wire in the ceiling. The ceiling light needs to be connected to the switched leg conductor coming off of the switch in order for it to work.

How do you fix a ceiling light that won’t turn on?
If a problem remains, be sure the switch is off, remove the bulb and substitute a new one. If the light does not work with a new bulb, check whether the circuit breaker or fuse governing the fixture has tripped or blown. This often happens when a bulb burns out the moment it is turned on.
Why won’t my LED bulbs turn off?
These dimmers need a minimum load for correct function which is not achieved by the economical design of LED lamps. If the load falls below the minimum load, the dimmer cannot switch off its output voltage completely even in the off position. As a result the LED continues to glow weakly.
Why do lights stay on all the time?
Because they are florscent bulbs. The phosphor in them keeps glowing for a while after they turn off.
Can a faulty light switch cause a fire?
Usually, a broken or failing light switch isn’t a fire hazard itself, but it can overheat if the contacts or the switch wear down. Sometimes a bad light switch can cause other components on the circuit, such as a bulb, to become a fire hazard by causing an intermittent current.
How can you tell if a light switch is bad?
The first sign of trouble is when the switch begins to behave in a fashion that is abnormal in any way. For example, if there’s an audible crackle, snap, or popping sound when you flip the lever, then it’s pretty clear that your switch is defective and it’s time to replace it.
Why is my ceiling fan light not turning off?
When the switch won’t turn the ceiling fan off, or even when the ceiling fan light won’t turn off, the first thing to do is to try and turn the fan off any other way. In most cases, this means using the pull chain. Many fans also have a pull chain dedicated to the lights only, so you should check that one as well.
How do you fix a light switch button?
Quote from Youtube video: Head but sometimes you can use a flathead screwdriver I prefer a Phillips just because I get more. It's just easier to turn. But you just remove this plate.
How do you fix LED ghosting?
3 options here:
- Change the LEDs to an approved product- may not solve the problem.
- Change dimmer to the PD-6ANS- most likely would solve or at least reduce the “ghosting” you are experiencing.
- Try the LUT-MLC- lots of posts on this, Lutron reluctantly has mentioned the MLC with dimming now.
Is it normal for LED lights to glow when off?
So, essentially, if your LED bulb is giving off a dim light even when it’s turned off, this isn’t an indication that there’s something wrong with the bulb but rather that your lighting fixture still has a slight electrical current going through it even when it’s off.
What is light ghosting?
Ghosting is a faint lighting from residual current in the inserts. Strobing is actually seeing the cycle rate in a GI bulb. You are likely losing sight of the ball from the reflection of the light on the ball, even with frosted bulbs.
Why are my LED strip lights glowing when off?
To LEDs glow in this “off” state, it is most often necessary for the LED driver to be of non-isolated type, that is, the primary (230 volts AC) is not galvanically separated from the secondary side (X volts = when the driver is a voltage source or X Ampers = when is a current source).
Can LED strip lights cause a fire?
LED strips are pretty harmless. In extremely rare cases, they may cause a fire, but there is no risk apart from that. However, make sure you take good care of your lights. If well-maintained, there is nothing to worry about.
How do you turn off LED strip lights?
Since LEDs run on low voltage DC electricity, they require a power supply (sometimes called a transformer or driver) to convert from your home’s high voltage AC. You can switch off this electricity before it gets to the transformer with a regular on/off switch – usually mounted in the wall like a light switch.
What happens if your LED lights won’t turn on?
If your LED light strips will not turn on at all, it is likely a poor pin connection. This is akin to charging your cell phone or plugging anything into an outlet. If the metal prongs are not securely connected inside the outlet, you will not get the desired result.
How do you fix a LED ceiling light?
Quote from the video:
Quote from Youtube video: Pull the bracket lock and attach the lamp body to the fixed mounting bracket turn on the main switch and the lamp will light up immediately. And the installation will be completed successfully.
How do you reset LED lights?
There is no way to reset it other than unplugging and plugging back in again, usually after a power outage. If you have LED lights that turn on at random times during the day, then this likely needs to be done. Other reasons that you may need to reset your LED strip is if it does not work after being installed.
